.COCK.

SPECIFICATION forming part of Letters Patent No. 398,117, dated February19, 1889.

Application tiled December 6, 1888.

To @ZZ whom it may concern,.-

Be it known that I, GUSTAV A. BARTH, a citizen of the United States,residing at the city a certain new and useful Improvement in Cocks, ofwhich the following is a full, clear, and exact description.

My invention relates to an improvement in three-way cocks, and has forits object to obtain a simple and compact form of cock, wherebysteam,water, compressed air, or other fluid may be readily directedeither through an outlet-passage opposite to and in line with the inlet,along the shell and through an outlet-passage in line with the plug, orat right angles to the inlet.

On the accompanying drawings, Figure l represents a plan of my improvedthree-Way cock; Fig. 2, a side elevation thereof; Figs. 3 and at,Sectional elevations on lines l l and 2 2, respectively, in Fig. l; Fig.5, a similar view on line 3 3 in Fig. 4; Fig. 6, a sectional plan online 4 4 in Fig. 2; and Fig. 7, a similar view to Fig. 6, showing analtered position of the plug.

Like letters of reference denote like parts in all the iigures.

The plug a of my improvvd three-way cock is preferably made hollow,closed at both ends, and tted within the shell b in the usual manner.Through the circumferential wall of the l plug a are openings c c c?,the openings c c2 1 being opposite to each other and the opening c atright angles thereto. Through the shell b are corresponding passages, dd cl2, having l the same relative arrangement as the openl ings c c c2in the plug a. The passage d i opens into a pocket, e, formed in theshell and l extending' along the latter to a space, e', immediatelybeneath the bottom of the plug a, where it communicates with theoutlet-passage e2.

As seen in Figs.- l to 6, the plug a is so lo- I Serial No. 292,823..(No model.)

cated by its handle f that the openings c c2 of the plug a are oppositeto and communicate with the passages CZ d2, respectively, of the shellb, the opening c of the plug a being closed against the wall of theshell b, which also closes the passage cZ-that is to say, steam or otheriluid entering through the inlet-passage d, as indicated by the arrows,passes through the openings c c2 of the plug a and through theoutlet-passage cl2 in the shell b.

On giving the plug a a quarter-turn by its handle f in the directionshown by the dotted arrow in Fig. l the openings c c of the plug a arebrought opposite to and communicate with the inlet-passage d andoutlet-passage CZ', respectively, of the shell b, as shown in Fig. 7,while the opening c2 of the plug a and outlet-passage d2 of the shell bwill be closed by the wall of the latter, whereby steam or other iuidfrom the inlet-passage d passes through the openings c c of kthe plug aand through the passage d along the pocket e in the shell b, and thencethrough space e and outletpassage e2.

By this invention the steam or other fluid may be directed by a straightpassage through the cock from side to side, or at right angles theretoin line with the plug Without the aid of bends.

I claim as my invention- In a cock, the combination of a plug, d, havingopenings c c c2, and shell b, having openings (l d d?, with a pocket, e,and outlet-pasas shown, and for the purpose described.

In testimony whereof I affix my signature, in presence of two Witnesses,this 30th day of sage e e2, formed in said shell, substantially
